Pollen levels are currently low but are expected to rise due to climate change, leading to increased allergy prevalence. With about one in three Europeans affected now, this figure could reach one in two by 2050. The growth of allergenic plants and longer blooming seasons exacerbates the issue. Allergy sufferers are encouraged to monitor pollen forecasts and consider desensitization therapy. Preventive measures for children include a varied diet and protective skin care. Political action is essential for effective allergy management.
Pollen levels may be low for now, but that won’t last. Research indicates a rising trend in allergy prevalence throughout the year, largely fueled by climate change. So, what can individuals with allergies do to shield themselves?
The pollen season has kicked off, with the purple alder already past its flowering phase. However, this year’s onset is relatively mild compared to previous years. This is a relief for many, as currently, about one in three Europeans experiences allergies, and projections suggest this could rise to one in two by 2050.
The changing climate also supports the growth of invasive and highly allergenic plants, such as ragweed and the tree of heaven, in Germany. Concurrently, the allergy burden is on the rise due to extended blooming periods caused by increasing average temperatures.
Pollen Season 2024: Surging Levels for Specific Species
Last year’s data revealed unprecedented levels of birch and grass pollen, with ragweed contributing to particularly high pollen counts. This information was gathered through 35 rooftop monitoring stations across Germany.
These stations also aid scientists from the pollen information service in forecasting future trends. By 2025, despite a mild start to the season, pollen dispersal is expected to escalate rapidly. The alder is set to bloom soon, and other trees like cypress could further elevate pollen levels in the upcoming days and weeks.
In an exciting development, the first emergency nasal spray for allergy sufferers is anticipated to be available by the end of 2024.
Effective Strategies for Allergy Sufferers
Allergy sufferers can take significant steps to alleviate their symptoms, according to Claudia Traidl-Hoffmann, a professor of environmental medicine at the University of Augsburg and director of the Institute for Environmental Medicine at the Helmholtz Center in Munich. She advises individuals to monitor pollen forecasts daily, avoiding outdoor activities during peak pollen times. Additionally, washing hair before bed can help reduce pollen accumulation on bedding.
Furthermore, allergies and allergic asthma can be treated effectively. Desensitization, also referred to as specific immunotherapy, is a method where individuals receive gradual exposure to small amounts of the allergen over a period of up to three years. This process helps the immune system adapt to the allergen, ultimately reducing or potentially eliminating allergy symptoms over time.
In Germany, around three million people are affected by allergies to bee or wasp venom.
Preventing Allergies in Children
Parents can take proactive measures to prevent allergies and allergic asthma in their children. According to environmental medicine expert Traidl-Hoffmann, a varied and plant-based diet during the first two years of life is crucial. For children at greater risk—especially if both parents have allergies—using special creams free from fragrances and harmful substances can help strengthen the skin’s natural protective barrier.
The Role of Policy in Allergy Management
Experts stress the importance of political action in addressing allergies. Public planning should take allergies into account, particularly in schools, workplaces, and urban development. Claudia Traidl-Hoffmann emphasizes, “Climate change and allergies are closely intertwined. By safeguarding the climate, we also safeguard our health.”
